   CTA video — atmospheric "focus pulling" effect.
   Default state: scene is softly blurred and slightly desaturated,
   like an out-of-focus film still. The cursor pulls a sharp,
   warm spotlight through the scene; figures near the cursor
   come into focus and warmth, the rest stays dreamy.
   The whole panel breathes with a slow idle float.
